Centrifugal fans with forward curved blades

Cylindrical rotor fans in EC technology

Centrifugal fans with forward curved blades always require a spiral housing. Their characteristic features are a low noise level, relatively small air flow with a high increase in static pressure, and space-saving application.

Energy savings, convenient control and low noise - Cylindrical rotor fans with GreenTech EC technology

Saving energy is becoming an ever increasingly important topic these days. Especially when it comes to air-conditioning and ventilation technology, great potential savings can be achieved by using energy efficient fans. For this reason, motor and fan specialist ebm-papst has recognised the issue, and has developed a complete series of dual-inlet, direct-driven cylindrical rotor fans with efficient GreenTech EC technology. Without changing the design of the unit, this allows a conversion from a conventional fan with asynchronous motor to modern energy-saving technology.

With integrated motor electronics, the EC fans can be easily speed controlled via a 0-10 V signal or by the use of a potentiometer. As an option up to three air flow values can be programmed in "Constant Flow" mode. This means that if the system resistance changes, for example due to polluted filters, the fan keeps the programmed air flow by changing the speed automatically.

Depending on the motor type used, the double inlet fans with state-of-the-art EC technology cover almost every conceivable application area. You can choose between eleven sizes with drive outputs between 85 W and 3 kW. Thus a customised solution is available for virtually any application, including compact air handling units, air curtains, fan coil units, air heaters for factory buildings or as a cooling fan for forced cooling of power converters, generators or telecommunications systems.

Increasing energy costs and legal regulations contribute to the fact that the comprehensive consideration of buildings in terms of their efficiency is playing a bigger and bigger role. High energy savings potential can be attained if the right technology is used in ventilation and air-conditioning technology such as for climate control systems where the fans run almost around the clock.

GreenTech EC-Technologie: das Original

GreenTech EC technology: the original.

The advantages of EC fans speak for themselves. Because the electronically commutated external rotor motor is integrated within the forward curved impeller, the installation dimensions are reduced and there is no longer any need for the commonly required belt drive between the motor attached on the outside and the impeller. This reduces the fan dimensions always desirable for ventilation and air-conditioning technology as well as the associated installation effort.

Furthermore, the electronically commutated motors are extremely quiet and operate at efficiencies of up to 90 %. Thus they attain significantly higher values than most voltage-controlled asynchronous motor, which have typical efficiencies of between 30 % and 60 %. At the same operating point, therefore, the power consumption of the EC fans is considerably less.
